When choosing to wear your hair down for your bridal look or another event, it's worth thinking about how it will sit over your shoulders. This depends on the look you're going for, but a few other factors matter too.
We tend to play with our hair throughout the day without noticing — pulling it both to the front, one side forward, or all the way back. Pay attention to which you naturally gravitate toward, and choose a hairstyle that matches, so it's easier to keep in place.
For a bridal look specifically, think about how many people are going to hug and kiss you. Having your hair pulled back on one side leaves you a free shoulder for hugs, without disturbing your hairstyle — keeping it flawless for as long as possible.
